Summer Heat Stress in the Garden – In this video I show some heat stress related photos from the garden and go over some best practices to how to avoid summer heat problems. 100-degree days can be very tough on gardens and landscapes.

Great video Jim! I’ve had many plant suffer from the heat we had back in July. I garden in Las Vegas NV Zone 8b and our hottest day was 117. It was brutal on my plants. I lost some of them while others have defoliated due to burnt leaves. It’s so sad 😢 to see, but I’m hopeful they will bounce back now that our temps are under 100 degrees. 😂
I can't tell you how much better this makes me feel about my very first foundation plants I put in this year that are STRUGGLING.
Thanks Jim. Needed this. Its been a rough summer.
Thanks!
This was great information. I especially appreciate how you incorporate a little bit of horticulture science into your presentations.
Thanks for the video Jim. This has been an exceptional gardening year. The heat and humidity is hard to garden in. I did a lot of my watering early in the mornings before sunrise. I wanted you to know i followed your good advice and left my azaleas that i thought the cold snap at Christmas had killed alone. They looked like dead twigs in the ground. Most all of them came back and look nice and healthy even after the heat. I only had to replace three that were planted in late September last year. Plants are more resilient than we give them credit for.
what a stark contrast to the climate here in california currently. It's been the mildest summer I've ever encountered, and the plants are thriving and growing too much. Normally it's 100+ degrees, but the average has been hovering around 80 degrees. Guess some years you get lucky
To me,,,,,watering plants that are in the ground this time of the year is tricky…phytophthera loves heat and moisture so if it gets water in the heat of the summer,,,,watch out, things will die even though they are being watered…
watering in pots is a totally different thing…potted stuff must be watered….
My dogwoods took a hit.
Very helpful Thanks.
Thank you very much. This was very interesting and extremely useful.
I solved the issue with my hydrangea's scorched leaves by giving it some water daily, aside from the scheduled watering. I noticed which plants seemed to have the most heat related issues. Some plants have to be babied more during the summer.
Jim any plant recommendations for west side of my house that only gets 2.5-3 hours of direct afternoon sun? Missouri zone 6a.
I prob planted over 75 new plants with no irigation this summer. Trying to keep up with the watering has been very time consuming. Hoping next summer would be better.
Jim – do you know anyone that is gardening in North Texas like you are? We need someone since the garden centers really are no help. But your message was loud n clear “plant now- and mulch” so we can better manage the coming years of heat 100 degree temperatures. You are a master of this stuff and your years of suffering resulted in your beautiful garden today.
Jim – I VOLUNTEER my garden as your 2024 project to help us all in Texas!🎉
Zone 9b south Texas here and feeling very defeated so thank you for this information!! Gives me hope for my garden 💚
Not familiar w your channel but out of desperation I searched & you came up!😊
I was going to attempt to cut clean up a couple plants & trees as we just went thru mandatory evacuation due to the hurricane. I was discouraged because where I rent she (landlord) has no interest as she wants to sell.
I asked begged for a year which she signed. HOA mowes etc. But still a few things need done. For a man np but for me i just want it done & cheap because I don't have to pay & do this I rent. It is honestly for me.
Sunny Hot humid maybe snake or 2 as always.
No motivation
I need a yard lover
I'm not anymore.
I want to go to the beach.
No I need help wish you could just do & I return and super cheap. The lawn companies are expensive & guage prices! Do you know anyone down south as in south Tampa Fl?
We don't get 100-degree weeks anymore in Texas, we're now seeing 100-degree months. It's becoming really difficult to figure out what will and won't survive.
Great info for a new gardener. Thank you.
Great advice.
Thank you so much for sharing this information. I’m in N.Dallas, Texas and this summer has been brutal. Watering a lot and Umbrellas. Thankfully everything survived.
Thanks for making this video. My rising sun redbud is suffering.
Thanks for info!
For the first time my hostas under my big oak showed stress, dropping and burning leaves. I will watch and if it happens next year I will move them to deeper shade.
So interesting, thank you!
Thanks for such good information. I wish Texas had only weeks of 100 plus temps. We have had months and almost no rain, which hopefully we will get relief starting today 🙏
Thank you Jim! Worried we lost a lot of smaller plants this year in zone 7A VA. Hellebores and Coral Bells especially took a hit. Any suggestions on lace bug on azaleas? We have dozens and they all have lace bugs. Very established shrubs, but look worse then I’ve ever seen. I’ve waited to treat do to heat. TIA for any wisdom.
Here in Central Texas, we received 0.35" of rain yesterday. Not exactly a big storm, but it finally dropped us out of the heat wave we've had since early July, and it's the most rain we've seen in a 24-hour day since mid-June. The latter part has been more depressing than the heat wave, and that's saying something.
Between 2am and 3:30am this morning, another 0.25" of light rain fell, then the spigot finally opened. Between 3:30am and 5am, we received 1.85", giving us 2.1" between 2am and 5am. Biggest storm we've had since May 2023.
Sooo helpful. As always, such masterful, experience-basted information.
I wish all the water I see being wasted for unnecessary irritation here in Michigan this year I could send to y’all that need it. Cause we’ve had a cool wet season aside from May and part of June. But soooo many people set it and forget it and I see it run rain or shine cause why have a rain sensor for an extra $75
What about Steeds Holly? The leaves have turned yellow. I am in zone 8.
Thanks for this video, Jim. I’m late watching but it was very helpful. I’ve seen some of everything you described, but less this year than last as my plants have become more established. Some plants that burned last August showed no signs of stress in the late summer heat this year. Newly planted butterfly bushes are a little crispy and now appreciating the first half inch of rain we’ve had in months.
